An hour or two to be safe. But truthfully, most turn the water back on within a few minutes.

Supposed to wait at least a day for the glue to cure, but most don't wait that long.

what the base question??

the glue literally melts the pipes together.. no need to wait .. it either worked.. or it didnt ...

if the concern is off gassing or some such ... just run the water.. let it stand over night.. and use it ... on the pipes.. it dries in seconds ....

you arent going to drink from it immediately are you ... whats the concern???

quick call to a friendly plumber or even a good hardware store.. might get you a real fast. good.. answer ... i see you included the plumbing forum.. if active.. we should get an answer ...

im curious about the whole system.. is this just a supply line .. which then will have some type of irrigation installed onto it????
